WhatsObservable 0.1.0

Determine which small solar system bodies are observable from a given location at a given time

===============WhatsObservable===============

WhatsObservable is used for determining which minor planets (and comets) are observable at a given time from a given location on Earth.

WhatsObservable determines the locations of objects using the routinesof [PyEphem]http://rhodesmill.org/pyephem/ and the[Minor Planet Center's Orbit Database]http://www.minorplanetcenter.net/iau/MPCORB/MPCORB.DAT)*Note that at least for the time being the user must download this file separately and WhatsObservable will find it on disk.*

The intent is to replicate the functionality available at the [JPL Solar SystemDynamics Small Body Whats Observable web page]http://ssd.jpl.nasa.gov/sbwobs.cgi)The motivation for writing WhatsObservable was to provide this capability whenoffline and in an easily scriptable manner.

NOTE: The precision of PyEphem with the MPC Orbit Database is good, especially fordates near the orbital epoch, but is not nearly as good as what is available directly from the [JPL Horizons System]http://ssd.jpl.nasa.gov/?horizons) Evennear the orbital epoch errors of a few arcseconds are not uncommon. Use thistool at your own risk and if precision matters, refer back directly to the[JPL Horizons System]http://ssd.jpl.nasa.gov/?horizons)
